1 answer

To find an equation that would make sense for Kelia's second step of multiplying both sides by 4, let's analyze the options provided:

  1. \( 6 + \frac{x}{4} = 1 \)
  2. \( 6 + 4x = 1 \)
  3. \( \frac{x}{6} = 1 \)

From these, if she multiplies both sides of the equation by 4, we need to see which would yield a valid transformation.

  1. For \( 6 + \frac{x}{4} = 1 \):

    • Multiply both sides by 4:
    • \( 4(6 + \frac{x}{4}) = 4(1) \)
    • This simplifies to \( 24 + x = 4 \), which is valid.
  2. For \( 6 + 4x = 1 \):

    • Multiply both sides by 4:
    • \( 4(6 + 4x) = 4(1) \)
    • This simplifies to \( 24 + 16x = 4 \), which is also valid.
  3. For \( \frac{x}{6} = 1 \):

    • Multiply both sides by 4:
    • \( 4(\frac{x}{6}) = 4(1) \)
    • This simplifies to \( \frac{4x}{6} = 4 \), which is also valid but not leading to a straightforward relationship connected to the other equations.

However, only the first one leads to a more meaningful transformation (getting \( x \) alone is much easier).

Given all three options, the clearest equation where multiplying by 4 has a practical sense in solving for \( x \) is:

6 + \( \frac{x}{4} = 1 \)

Thus, the answer is 6 + \( \frac{x}{4} = 1 \).
